Figure 8 is an end elevational view of a still further modiiied form ofthe invention in which a bristle brush is substituted for the applicatorroller shown in the previously described iigures, and

Figure 9 is an end elevational View of still another modied form of theinvention which is similar to the form shown in Figures l to 4 inclusivewith the substitution of an agitator roller for the sinuous or helicalwire agitator employed in connection with the form of the inventionshown in Figures l to fi inclusive.

In the drawings, and more in detail, attention is first directed to theform of the invention illustrated in Figures l to 4f inclusive whereinfor the purpose of convenience of illustration there is shown a safetyrazor of conventional design generally designated 5 upon which thelather applicator generally designated is adapted to be removablyattached. The safety razor 5 may be of any well known make and the typeillustrated includes a handle 1 having a knurled hand grip portion andan internally threaded bore il at one end thereof for receiving thecorrespondingly threaded stud 9 of the blade clamping cap iii. A guardII is received on the stud 9 and the comb edges or ends I la of theguard are directed away from the cap i to provide a rounded surface onthe ends of the guard teeth and eliminate sharp points, The blade i2likewise of conventional design is held between the cap IIB and guard IIby the clamping action of the handle 1 and stud 9.

The lather applicator includes a base plate I5 of a size and shape to bereceived beneath the guard II with the side edges thereof abutting thedownwardly turned guard teeth IIa. The

base plate I5 is of a length substantially equal to the length of theguard II, and is provided with a central opening I6 adapted toaccommodate the stud S when the plate i5 is in position as shown inFigure 2. In addition, openings I1 are formed in the plate one on eachside oi the opening I6 to accommodate correspondingly positioned bladecentering pins usually carried by the cap Il] on certain types of safetyrazors.

The openings I5 and I1 are connected by longitudinal slots I8 which arearranged such as to adapt the device to various other types of safetyrazors now on the market. Formed integral with the base plate I5 on oneedge thereof adjacent each end is a bearing loop I9, between which issupported a pintle 2D which extends along the underside oi' the baseplate when the assembly is in position as shown in Figures 2 and 5.

Hingedly connected to the supporting plate I5 is an applicator rollerframe 22 having formed intermediate its ends a pintle loop 23 whichprojects into a cut-away portion 24 of the base plate I5 and encirclesthe pintle 20. rPhe loop 23 terminates in a curved extension 25 which isadapted to be engaged by the finger of the user when the latherapplicator is being manipulated to apply lather to the face and saidcurved projection is also adapted to form a stop for the hinged frame 22when the device is used for applying lather and simultaneously shaving.

Formed on the frame 22 is a pair o roller supporting arms 26 arrangedone adjacent each end of said frame, and the free ends of each of theroller supporting arms 26 are provided with bearing openings forreceiving the ends of a roller supporting shaft 21. An applicator roller28 is supported by the shaft 21, and said roller is preierably formed ofa resilient yielding sponge-like material such as sponge rubber.

Also mounted on the hinged frame 22 and supported between the arms 26is.a sinuous or helical bar 30 which has its ends received in openingsin the roller supporting arms 26 and aiflxed thereto. The bar 30 isadapted to contactually engage spaced apart portions on the peripheralsurface of the roller 28 to create foam by the frictional engagement ofsaid bar. As illustrated in Figure l the bar 30 is of undulating shapeand arranged so that spaced apart portions will frictionally engage theperipheral surface of the roller 28 during rotation thereof and create afoaming action so that an ample supply of lather will be formed on theperipheral surface of the roller for being applied to the face of theuser.

In operation, the base plate I5 is affixed to a conventional safetyrazor by being attached as shown in Figure 2 such that the lingerprojection 25 extends in a direction beneath the guard and cap of thesafety razor. After the lather applicator has been thus applied to thesafety razor a lather solution formed of soap and water is applied tothe roller 28 either by immersing the roller in the solution or coatingthe same in any suitable convenient manner. The handle of the safetyrazor is then grasped by the user and the razor and applicator aremanipulated as shown in Figure 3 to apply a lm of lather to the usersface. The device is moved to and fro with the roller in facial contactso that the undulating rod 30 will produce a sufficient amount of foamylather to soften the beard.

During the lathering operation the forenger of the user is pressedagainst the iinger projection 25 to hold the applicator roller 28 in itsextended position as shown in Figure 3. When the beard has beensufficiently wetted and lathered, the roller supporting frame 22 isswung to the position shown in Figure 4 so that the finger projection 25engages the neck of the handle 1, ln this position, the safety razor 5can be used for the shaving operation with the roller 28 moving inadvance of the cutting blade I2 so as to apply lather additionally andsimultaneously cause the skin surface in advance of the razor blade tobe maintained in a semi-stretched or taut position. Thus, the razor willcut the hair in closer relationship to the skin surface and produce asmooth and close shave. It is to be noted, that during the shavingaction, the roller 28 also produces a massaging effect and kneadingaction which enhances the appearance of the user and creates astimulating eiect upon the users face.

When the user has nished shaving, the varous parts of the razor may beremoved and. the roller applicator likewise removed to facilitatecleaning by rinsing the roller in much the same manner in which thesafety razor parts are rinsed after use.

It is to be noted that when the applicator roller 28 is in the positionshown in Figure 2, the frame 22 engages the guard bar IIa of the guardII 2gsm-sse guard bar Ila. InJ the-other position as shown in Figure'v 4whereinthe applicator roller travels in advance of the safetyrazorduring shaving, the finger projection 25 engages the necked-inportionofv the handle and provides a stop for limiting swinging movement of theframe and roller in an opposite direction.

In' themodifed formk of the invention shown in Figure 5,.the safetyrazor 5a, includes a handle lo' as well as a cap'laand guard 'da ofasliglitly modified construction. The blade 12a is clamped betweentheguard 3 la, and theeap by the threadedstud 9a in muchthesame manneras described is provided adjacent its ends with depending lugs 32ahaving4 bearing openings 33a for receiving a pintle pin 34a; Theapplicator is identical to the applicator 6 shown in Figures l to l andincludes a frame 22a having a central projection 25a which is curved andlooped as at 23a to surround the pintle pin 34a. An extension 29a isformed on the hinge pintle loop- 23a and terminates in a finger engagingstop similar to the stop 25, Figures 1 to 4 inclusive;

The frame 22a is provided with roller supporting arms 26a having a shaft2?@ for supporting the yielding sponge-like applicator roller 28a whichas pointed out in Figures 1 to 4 is formed of sponge rubber or similarporous material. Also supportedv between the arms 26a is a sinuous orspiral rod 30a which is' similar to the sinuous 30 shown in Figures 1 to4i, and produces the same agitating action to create foam on theperipheral surface of' the applicator roller.

In the modified form of the invention shown in Figure 6, there isprovided a base plate [5b having a central opening lh which is similarto the base plate shown in Figures l to 4', and is provided with bearingloops adjacent each end i.

(not shown) for accommodating the ends of a pintle pin Zlib. Theapplicator is likewise similar 'to that shown in Figures l to l andincludes a frame 22h having a central projection bent as et 231i to formThe .free end ofy formed on the frame and are provided adjacent theirends with bearing openings for supporting a shaft 2lb upon which thesponge rubber plicator roller-28h 1s mounted.
